Chapter 1: Exploring Life Flashcards
organisms, such as animals, that feed on producers and other consumers
cosumers
DNA is the substance of ______, the units of inheritance that transmit information from parents to offspring
genes
The entire “library” of genetic instructiond that an organism inherits
genome
subdivided by internal membranes into various membrane-enclosed organelles including chloroplasts
Eukaryotic cell
Dna is not separated from the rest of the cell by enclosure in a membrane bounded nucleus
Prokaryotic cell
Example of ______ are cells, organisms, and ecosystems
system
due to the arrangement and interactions of parts as complexity increases
emergent properties
reducing complex systems to simpler components that are more manageable to study
Reductionalism
Ultimate goal of __________ is to model the dynamic behavior or whole biological systems
systems biology
accumaltion of a end product of a process slows that process
negative feedback
end product speeds up its production
positive feedback
a search for information and explanation often focusing on specific questions
inquiry
recorded observations
data
Describes natural structures and processes as accurately as possible through careful observation and analysis of data
discovery science
mostly about explaining nature
hypothesis based science
often in the form of recorded descriptions rather than numerical measurements
qualitative
generally recorded as measurements
quantitative data
derive generalizations based on a large number of specific observations
inductive reasoning
a tentative answer to a well framed question
hypothesis
the logic flows in the opposite direction, from the general to the specific
deductive reasoning
- much broader in scope that a hypothesis
- general enough to spin off many new specific hypotheses that can be tested
- generally supported by a much more massive body of evidence
theory
Plants and other photosynthetic organisms that convert light energy to chemical energy
Producers
